This manuscript is from what is known as a glossed Bible. Beginning in the twelfth century, the books of the Bible were often copied with commentary compiled from various sources, including the Church Fathers, St. Jerome, and other medieval exegetes. The layout and presentation of the text helps the reader to distinguish between what is Scripture and what is commentary. The large double-spaced script in the center of the page is Scripture; the gloss is written in the smaller script on single-spaced lines and sometimes in the space between the lines of Scripture.
